Command: ip igmp access-group {<acl_num | acl_name>}
no ip igmp access-group
Function: Sets the filter criteria for IGMP group on the interface; the “no ip igmp access-group”
command cancels the filter criteria.
Parameters: {<acl_num | acl_name>} is the sequence number of name of the access list, where the
range of acl_num is 1 to 99.
Default: No filter criteria is set by default
Command mode: Interface Mode
Usage Guide: This command can be issued to filter the groups on the interface to allow or deny the
participant of some groups.
Example: Specify interface vlan1 to permit 224.1.1.1 and deny 224.1.1.2.
Switch (Config)#access-list 1 permit 224.1.1.1 0.0.0.0
Switch (Config)#access-list 1 deny 224.1.1.2 0.0.0.0
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp access-group 1
Command: ip igmp join-group <A.B.C.D >
no ip igmp join-group <A.B.C.D >
Function: Joins the interface to an IGMP group; the “no ip igmp join-group” command cancels
the join.
Parameters: <A.B.C.D> are the IP addresses for multicast groups.
Default: not joined to groups.
Command mode: Interface Mode
Usage Guide: When a switch is used as a host, this command is used to any the host to a group.
Suppose the local interface is to be added to group 224.1.1.1, then the switch will
send a IGMP member report containing group 224.1.1.1 on receiving IGMP group
query from the other switches. Note the difference between this command and the
“ip igmp static-group” command.
Example: Specifying interface vlan1 to join group 224.1.1.1.
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp join-group 224.1.1.1
